a Chemical bonding of Rose Bengal to aminated metal@silica nanoparticle, reproduced from Ref. [223] with permission from American Chemical Society. b Distance-dependent ME-SOG of Rose Bengal on 67 nm Ag nanoparticle coated with silica shell, reproduced from Ref. [223] with permission from American Chemical Society. c The first-order kinetic data for degradation of ABDA molecules in the presence of Rose Bengal molecules bonded on silver nanocube coated with silica shell (Ag@SiO₂-RB NC) and the etched sample as control, and under similar white light irradiation, reproduced from Ref. [224] with permission from American Chemical Society. d (i) Layer-by-layer approach to control the distance between metal core and photosensitizer by tuning the thickness of dielectric bilayer on metal nanoparticles surface. (ii) Simplified Jablonski diagrams showing the MEF (right scheme) and ME-SOG (left scheme) mechanism of the AIE-PS nanohybrids occur at different optimum AgNPs to AIE-PS distance for maximum plasmonic enhancement, reproduced from Ref.
